Cleaning mechanism & how a strong leather cleaner works

Leather Cleaner Strong uses powerful yet leather-friendly surfactants that lift dirt, grease and deep-set particles off the pigmented surface. Since modern automotive leather has a PU topcoat, grease and abrasion tend to settle into the micro-structure of that layer. The cleaner breaks those bonds without softening the protective coat. According to the maker, the formula is dialled in to be strong enough for stubborn residue yet soft enough to keep the matte factory look. On greasy steering wheels you really see it work: it pulls the oils out of the grain and brings back the original grip and the matte finish.

Prep, application & the best cleaning routine

Before you get going with Leather Cleaner Strong, knock off loose dirt with a microfibre cloth. You put the cleaner onto a cleaning pad, a brush or a cloth — never straight onto the leather. Work the foam in with circular motions until the dirt lets go. Then wipe the residue off with a clean, slightly damp cloth. On really greasy spots like steering wheels you may need a second pass. After every deep clean it pays to follow up with a matched care product or a rub protector, so the leather stays supple and dirt has a harder time taking hold next time.

Results, typical use cases & where it differs from mild cleaners

After the treatment the leather looks cleaner, more matte and feels noticeably grippier. Heavy soiling, shiny patches from skin oils and worked-in abrasion are clearly reduced or fully gone. The Strong Cleaner is the one to reach for on heavily used cars, full reconditioning jobs, lease returns or older interiors. For light dirt, though, the mild version is enough to clean the surface gently. The Strong Cleaner is no substitute for scratch or colour correction — for visible wear in the pigment layer, products like Leather Fresh or Fluid Leather are the way to go.

Common questions about COLOURLOCK Leather Cleaner (Strong)

Can I use the Strong Cleaner on any leather?

Only on pigmented smooth leather. For aniline, nubuck or sensitive leather, the mild cleaner or a dedicated product is the better call.

Does the cleaner attack the colour?

No, not on pigmented leather. It lifts dirt and grease without loosening the colour layer.

How often can I use the Strong Cleaner?

Only when you need it. For regular care, the mild cleaner does the job.

Why does the leather look more matte after cleaning?

Because the grease and dirt that were creating the shine are gone. That's a normal, intended result.

Do I have to condition after cleaning?

Yes. A care product or a rub protector locks in the result and cuts down on dirt building up again.
